Kyoukai Senjou no Horizon story is set in the future, Humans live in a small piece of Earth, which is still habitable, demons and other creatures inhabiting the same place. The soundtrack is amazing. The anime has lots of action that you'll enjoy very much the first time you watch it. The production values from character designs to animation, voice acting and soundtrack are excellent. Kyoukai Senjou no Horizon is one of those anime that have so much potential. I can definitely say that I enjoyed this anime after watching it.
